Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595006, here are decompositions:

7 + 31594999 = 31595006
19 + 31594987 = 31595006
43 + 31594963 = 31595006
103 + 31594903 = 31595006
139 + 31594867 = 31595006
193 + 31594813 = 31595006
199 + 31594807 = 31595006
277 + 31594729 = 31595006

Showing the first eight; more decompositions exist.
